Well good for him. This is a worthwhile charity. It has been proven time and again that doggies (or pets as a whole for that matter) greatly enhances people's lives. In fact, Mr. Russo and I like to help out a charity called Project Pooch where they pair a juvenile delinquent with a dog to train, take care of and then place in a forever home. (pooch.org) The impact on the former offender's life and the dogs is changed for the better. Many servicemen and women are given a dog here in the states to help them cope with PTSD.
I think Prince Harry has the right idea with this one and hope he continues with a patronage or more.

Prince Harry attended the Friends of the Forces Awards at the Liberal
Club on July 13, 2010 in London, England. The Prince presented the
first award at the event which recognises people from across the UK
who make an outstanding contribution to service personnel and their
families.

I agree, and he is making a good showing of himself as well!
Project Pooch in Oregon, run by Joan Dalton has been copied in many different areas of the US. I can't be certain though I think a version has also jumped the pond to England.
